Optical Cards

This chapter describes the Cisco ONS 15454 SDH optical, transponder, and muxponder card features and functions. It includes descriptions, hardware specifications, and block diagrams for each card. For installation and card turn-up procedures, refer to the Cisco ONS 15454 SDH Procedure Guide.

4.1 Optical Card Overview

Note Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 shelf assembly. The cards are then installed into slots displaying the same symbols. See the "1.12.1 Card Slot Requirements" section on page 1-15for a list of slots and symbols.

The OC48 ELR/STM16 EH 100 GHz card provides one long-range (enhanced) STM-16 port and operates in Slots 5, 6, 12, or 13. This card is available in 18 different wavelengths (9 in the blue band and 9 in the red band) in the 1550-nm range, every second wavelength in the ITU grid for 100-GHz spacing dense wavelength division multiplexing (DWDM).

The OC192 LR/STM64 LH ITU 15xx.xx card provides one extended long-range STM-64 port and operates in Slots 5, 6, 12, or 13 with the XC10G card. This card is available in multiple wavelengths in the 1550-nm range of the ITU grid for 100-GHz-spaced DWDM.

Note The Cisco OC3 IR/STM1 SH 1310-8, OC12 IR/STM4 SH 1310, and OC48 IR/STM16 SH AS 1310 interface optics, all working on 1310 nm, are optimized for the most widely used SMF-28 fiber, available from many suppliers.

Corning MetroCor fiber is optimized for optical interfaces that transmit at 1550 nm or in the C and L DWDM windows, and targets interfaces with higher dispersion tolerances than those found in OC3 IR/STM1 SH 1310-8, OC12 IR/STM4 SH 1310, and OC48 IR/STM16 SH AS1310 interface optics. If you are using Corning MetroCor fiber, OC3 IR/STM1 SH 1310-8, OC12 IR/STM4 SH 1310, and OC48 IR/STM16 SH AS 1310 interface optics become dispersion limited before they become attenuation limited. In this case, consider using OC12 LR/STM4 LH 1550 and OC48 LR/STM16 LH 1550 AS cards instead of OC12 IR/STM4 SH and OC48 IR/STM16 SH cards.

With all fiber types, network planners/engineers should review the relative fiber type and optics specifications to determine attenuation, dispersion, and other characteristics to ensure appropriate deployment.

4.1.2 Card Compatibility

Table 4-2 lists the CTC software compatibility for each optical card. See Table 2-5 on page 2-4 for a list of cross-connect cards that are compatible with each optical card.

4.2 OC3 IR 4/STM1 SH 1310 Card

The OC3 IR 4/STM1 SH 1310 card provides four intermediate or short range SDH STM-1 ports compliant with ITU-T G.707 and ITU-T G.957. Each port operates at 155.52 Mbps over a single-mode fiber span. The card supports VC-4 and nonconcatenated or concatenated payloads at the STM-1 signal level.

4.2.1 OC3 IR 4/STM1 SH 1310 Functionality

You can install the OC3 IR 4/STM1 SH 1310 card in Slots 1 to 6 and 12 to 17. The card can be provisioned as part of a subnetwork connection protection (SNCP) ring or linear add-drop multiplexer (ADM) configuration. Each interface features a 1310-nm laser and contains a transmit and receive connector (labeled) on the card faceplate. The card uses SC connectors.

The OC3 IR 4/STM1 SH 1310 card supports 1+1 unidirectional and bidirectional protection switching. You can provision protection on a per port basis.

To enable an MSP-SPRing, the OC3 IR 4/STM1 SH 1310 card extracts the K1 and K2 bytes from the SDH overhead to perform appropriate protection switches. The data communication channel/generic communication channel (GCC) bytes are forwarded to the TCC2 card, which terminates the GCC.

4.2.2 OC3 IR 4/STM1 SH 1310 Card-Level Indicators

4.7.1 OC12 IR/STM4 SH 1310-4 Card Functionality

You can install the OC12 IR/STM4 SH 1310-4 card in Slots 1 to 4 and 14 to 17. The card can be provisioned as part of an SNCP, part of an multiplex section-shared protection ring (MS-SPRing), or in an ADM/TM configuration.

Note If you ever expect to upgrade an OC-12/STM-4 ring to a higher bit rate, you should not put an OC12 IR/STM4 SH 1310-4 card in that ring. The four-port card is not upgradable to a single-port card. The reason is that four different spans, possibly going to four different nodes, cannot be merged to a single span.

4.10 OC48 ELR/STM16 EH 100 GHz Cards

Eighteen distinct STM-16 ITU 100-GHz DWDM cards comprise the ONS 15454 SDH DWDM channel plan. This plan contains every second wavelength in the ITU grid for 100-GHz-spaced DWDM. Though the ONS 15454 SDH only uses 200-GHz spacing, the cards work in 100-GHz-spaced nodes, as well.

4.10.1 OC48 ELR/STM16 EH 100 GHz Card Functionality

You can install the OC48 ELR/STM16 EH 100 GHz cards in Slot 5, 6, 12, or 13. You can provision this card as part of a MS-SPRing or SNCP. In an ADM/TM configuration, you can provision the card as either an access tributary or a transport span interface.

Each OC48 ELR/STM16 EH 100 GHz card uses extended long-reach optics operating individually within the ITU 100-GHz grid. The OC48 ELR/STM16 EH 100 GHz cards are intended to be used in applications with long unregenerated spans of up to 200 km (with mid-span amplification). These transmission distances are achieved through the use of inexpensive optical amplifiers (flat gain amplifiers) such as erbium-doped fiber amplifiers (EDFAs). Using collocated amplification, distances up to 200 km can be achieved for a single channel (160 km for 8 channels).

Maximum system reach in filterless applications is 24 dB, or approximately 80 km, without the use of optical amplifiers or regenerators. However, system reach also depends on the condition of the facilities, number of splices and connectors, and other performance-affecting factors. The OC48 ELR/STM16 EH 100 GHz cards feature wavelength stability of +/- 0.25 nm. Each port contains a transmitter and a receiver.

The OC48 ELR/STM16 EH 100 GHz cards are the first in a family of cards meant to support extended long-reach applications in conjunction with optical amplification. Using DFB laser technology, the OC48 ELR/STM16 EH 100 GHz cards provide a solution at the lower extended long-reach distances.

The OC48 ELR/STM16 EH 100 GHz cards detect LOS, LOF, LOP, MS-AIS, and MS-FERF conditions. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide for a description of these conditions. The cards also count section and line BIP errors.

To enable an MSP-SPRing, the OC48 ELR/STM16 EH 100 GHz cards extract the K1 and K2 bytes from the SDH overhead. The GCC bytes are forwarded to the TCC2/TCC2P card; the TCC2/TCC2P terminates the GCC.

Card-Level LED

Description

Red FAIL LED

The red FAIL LED indicates that the card's processor is not ready. The FAIL LED is on during reset and flashes during the boot process. Replace the card if the red FAIL LED persists.

Green/Amber ACT LED

The green ACT LED indicates that the card is carrying traffic or is traffic-ready. The amber ACT LED indicates that the card is in standby mode or is part of an active ring switch (BLSR).
